According to the embodiment of the utility model, the wiper rubber strip comprises: a rubber strip mounting part 1, a rubber strip wing part 2, a rubber strip shoulder part 3 and a water scraping part 4.

Specifically, the top intermediate position of the adhesive tape wing part 2 is connected with the bottom intermediate position of the adhesive tape mounting part 1 through the first connecting part 5, the top intermediate position of the adhesive tape shoulder part 3 is connected with the bottom intermediate position of the adhesive tape wing part 2 through the second connecting part 6, and the top intermediate position of the water scraping part 4 is connected with the bottom intermediate position of the adhesive tape shoulder part 3 through the third connecting part 7; the width of the adhesive tape wing part 2 and the width of the adhesive tape shoulder part 3 are both larger than the width of the adhesive tape mounting part 1, and the position of the wiper part 4, which takes the third connecting part 7 as the center, for overturning and impacting the adhesive tape shoulder part 3 is not more than half of the width of the bottom end face of the adhesive tape shoulder part 3 impacted with the wiper part.

Therefore, according to the wiper strip of the embodiment of the utility model, by setting the width of the strip wing part 2 and the width of the strip shoulder part 3 to be larger than the width of the strip mounting part 1, the width of the strip wing part 2 and the width of the strip shoulder part 3 are widened compared with the position of the existing wiper strip, and the position of the wiper part 4, which is used for turning over the strip shoulder part 3 by taking the third connecting part 7 as the center, does not exceed half of the width of the bottom end face of the strip shoulder part 3 which is impacted by the strip shoulder part, so that the supporting force of the strip shoulder part 3 and the strip wing part 2 is improved, the turning noise caused by instant impact is reduced during impact, and the conventional wiper strip can be manufactured by simply modifying the die of the strip (the die corresponding to the strip shoulder part 3 and the strip wing part 2 is widened and modified).

As can be seen from fig. 1, the distance between the two ends of the shoulder portion of the adhesive tape, the width of the wing portion of the adhesive tape, and the width of the mounting portion of the adhesive tape are the same, when the wiper portion instantaneously impacts the shoulder portion of the adhesive tape, the position of the wiper portion impacting the shoulder portion of the adhesive tape is close to the end of the shoulder portion of the adhesive tape (refer to fig. 2 or 3), so that the supporting force of the shoulder portion of the adhesive tape is small, and the entire wiper adhesive tape is easy to be prone to be pressed. Compared with fig. 6, according to the wiper strip of the embodiment of the utility model, due to the widening treatment of the width of the strip wing part 2 and the width of the strip shoulder part 3, the position of the wiper part 4, which is used for turning over the impact strip shoulder part 3 by taking the third connecting part 7 as the center, does not exceed half of the width of the bottom end face of the strip shoulder part 3 impacted by the wiper part, so that the supporting force of the strip shoulder part is improved, the whole wiper strip is not prone to being pressed down, and the turning noise is reduced.

For the adhesive tape shoulder 3, the distance W3 between two ends of the adhesive tape shoulder 3 is the same as the width W2 of the adhesive tape wing part 2, so that the mold can be simply modified, and the width of the adhesive tape wing part 2 is widened, so that the adhesive tape shoulder 3 provides better supporting force.

More specifically, the width W2 of the strip wing 2 is 110% of the width W1 of the strip mounting section 1. That is, the width W2 of the tab portion 2 is widened by 10% over the width W1 of the tab mounting portion 1. It will be appreciated that the spacing W3 between the ends of the strip shoulder 3 is also widened by 10% over the width W1 of the strip mounting section 1. Therefore, under the condition that the adhesive tape shoulder 3 and the adhesive tape wing part 2 have better supporting force, the adhesive tape shoulder 3 cannot be turned over.

The width W2 of the tab portion 2 may be 7.0mm to 7.5mm.

Further, the shoulder 3 of the strip extends from the middle to the sides gradually in a direction away from the strip wing 2. Thereby, the wiper portion 4 is made to turn over the position of the impact adhesive tape shoulder 3 with the third connecting portion 7 as the center, not to exceed half the width of the bottom end face of the adhesive tape shoulder 3 impacted therewith; through the slope setting of adhesive tape shoulder 3, be convenient for scrape water portion 4 and be close to adhesive tape shoulder 3 to be convenient for scrape water portion 4 striking adhesive tape shoulder 3, and the widening setting of cooperation adhesive tape shoulder 3 makes the impact point not exceed the width of the bottom end face of adhesive tape shoulder 31, so, adhesive tape shoulder 31 can provide sufficient holding power, reduces the upset noise.

For the strip wing 2, the end of the strip wing 2 has an arc surface at the surface facing the strip shoulder 3. In this way, the support range of the adhesive tape wing part 2 is larger.

Further, the thickness of the tab wing 2 is greater than the thickness of the tab shoulder 3. Therefore, when the wiper strip turns over, the adhesive tape wing part 2 has better supporting force, and the adhesive tape shoulder part 3 can provide the supporting force of the wiper part 4 and can properly turn over to form damping buffer, so that noise is further reduced.

For the wiper portion 4, the tip end surface of the wiper portion 4 is a plane. That is, the longitudinal section of the wiper portion 4 is set to be inverted horn; the top end face of the wiper portion 4 is set to be planar so that the wiper portion 4 hits the adhesive tape shoulder 3 in the process of turning up, and the widening setting of the adhesive tape shoulder 3 is matched, so that the hit point does not exceed half of the width of the bottom end face of the adhesive tape shoulder 31, and thus, the adhesive tape shoulder 31 can provide sufficient supporting force to reduce turning noise.

For the first connecting portion 5, the first connecting portion 5 is perpendicular to the adhesive tape mounting portion 1, the first connecting portion 5 is arranged at the bottom end middle position of the adhesive tape mounting portion 1, and the first connecting portion 5 is of a strip-shaped structure. For the second connecting portion 6, the second connecting portion 6 is perpendicular to the adhesive tape wing portion 2, and the second connecting portion 6 is arranged at the bottom end middle position of the adhesive tape wing portion 2. As for the third connecting portion 7, the third connecting portion 7 is provided at a bottom end intermediate position of the bead shoulder 3. The third connecting portion 7 is provided in a strip-shaped structure, which can be bent under the drive of the wiper portion 4. Under the condition that the wiper part 4 wipes up or down along with the wiper arm, the wiper part 4 turns over under the action of the wiper arm so that one corner of the top end of the wiper part impacts the adhesive tape shoulder 3.
